Io's

Outland: An astonishingly underrated movie, if you can get past the handwaving tech to deal with Io's low gravity.

Given that Io's orbit around Jupiter is roughly the same size as that of the Moon around Earth, and Earth's diameter is roughly four times that of the Moon, and Jupiter roughly 10 times that of Earth, it seems that Jupiter would be 40 times bigger in the sky of Io than the Moon is in Earth's sky.

A related, cool, thing I was wondering: would you be able to see Io's shadow tracking across Jupiter as the 'night' progressed?

And if they're talking about rem, this is presumably a measure of gamma radiation probably a secondary product from magnetospheric charged-particle bombardment of Jupiter's outer atmosphere, or Io's own feeble salt-and-sulfur atmosphere, and would indeed at the doses you've uncovered require significant shielding.

Every month, for six straight months, Io appeared to take about 3½ minutes less to orbit Jupiter, so that after half a year, Io's orbit seemed to have shortened by 22 minutes.

And even if the suit did need to be extremely heavy, remember (a) that Io's surface gravity is only 18% that of Earth's, and (b) you can always fit the suit with a powered exoskeleton, as in Aliens.

Io's volcanoes might help explain changes in our own atmosphere.

Bosporus means in Greek "ox ford" or "ox passage"; the name comes from a Greek myth about Io's travels after Zeus turned her into an ox for her protection.
